I have the BMW sunshade for my E70 X5d. (Pictured below in my E53) I just started using the sundshade again as it's getting warmer outside. My car alarm keeps going off. I've determined my alarm is only going off on days I have the sunshade in the window. I've been disabling the interior alarm, and the alarm doesn't go off any more. This has happened in both of my E70s. It never happened in my E53. Anyone else have this issue?
